SPECIFICATION forming part of Letters Patent l lo. 641,226, dated January 9, 1900.. Application filed February Z0, 1892. Sam No. 422,318. (No model.)

To aZZ whom it may concern.-

Be it known that I, FEEEBCEN F. RAYMOND, 2d, a citizen of the United States, residing at Newton, in the county of Middleser': and State of Massachusetts, have invented a new and useful Improvement in Heel-Nailing Ma chines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part [0 of this specification, in explaining its nature.

The invention relates, first, to a heel-nailing machine having the nail-carrier and toplift-feeding slide connected with each other, whereby the movement of one causes the movement of the other; second, to an improvement in the nailing-jack; third, to an improvement in the heel-holding devices; fourth, to an organized heel-nailing machine having one reciprocation, wherein the last has two movements in relation to the templet during one reciprocation of the cross-head carrying the drivers and a top-lift-holding plate is moved into operative position after the first reciprocation of the last, but before thesecond.

It further relates to various details of organization and construction, all of which will hereinafter appear.

In the drawings, Figure l is a View in ver- 3o tical central section of a machine having the features of my invention. Fig. 2 is a view in side elevation, enlarged, of the improved jack. Fig. 3 is a view in front elevation thereof. Fig. 4 is view in plan thereof. Fig.

5 is a detail view, in front elevation, enlarged,

. to illustrate the connection between the top lift slide and nail-carrier. Fig. 6 is an enlarged view, in vertical section and elevation, to further show the connection between the top-lift slide and nail-carrier. Fig. 7isa view similar to Fig. 6, with the nail-carrier out of alinement with the templet. Fig. 8 is an elevation of the jacks with the shoe holders and guides. Figs. 9 and 10 are details, partly in section, of the guide-blocks. Fig. 11 is a detail in plan of the top-lift carrierand spankerplate, with breast and back gages. Fig. 12 is a view in front elevation of the machine. Fig. 13 is a view in horizontal section, en-,

larged, taken through the last and jack-post to Show the lateral movement of the former upon the latter. v

A is the frame of the machine.

a is an intermediate cross-support or table upon which the frame of the jack B rests.

a is an upper cross-support which carries the templet O and the nail-carrier D.

E is the power-shaft. It is connected by pinions (not shown) with gears (not shown) upon the shaft e. This shaft carries a pressure-cam e, which communicates vertical movement to a slide-head 6 adapted to have a vertical movement in the housing 0 F is a reciprocating cross-head upon which is mounted a block f, carrying a gang or group 6 5 of drivers f. This cross-head is connected with crank-pins carried by the gears upon the shaft 6 by means of connecting-rods. (Not shown.) The power-shaft E has a worm of, which meshes with the worm-wheel e on the vertical shaft 6 and this vertical Shaft carries a cam g, having a cam-groove to receive a cam-pin g, carried by the top-lift-carrier lever g This lever is pivoted to the bracket 9 at g and supports at its front end the toplift-spanker plate G, top-lift holders g and the heel-blank gages 9 His the top-liftfeed slide. It is mounted upon a table or support h (which preferably is yielding and vertically adjustable) to have a horizontal movement thereon or therein, and its inner end has the section or tongue h, which is in position under the stack k of top lifts in the position represented in Fig. 1, or preparatory to feeding the top lift, This tongue extends from the shoulder H, against which the breast of a top lift rests as it is fed to the receiving devices g of the top-lift carrier. The top lifts are held in position by the Stack-holder h it. (See Fig. 6.) The top-lift-feed slide is repreo sented as having a feed movement to feed the top lift from the table h to the top-lift carrier imparted to it by means of the bent lever 7L pivoted at h to the table a, one arm h of the bent lever extending from pivot-point to the top-lift-feed slide and the other arm h extending horizontally and having a handle it. The arm 72,7 is. connected with the top-lift-feed slide by means of a loose connection, represented in Figs. 6 and 7 as obtained by means of a stud h extending downward from the slide and having a pin 77, which enters a slot h in the lever. The lever h is also connected with the nail-carrier D by means of the link d, which extends from the lever to the nailcarrier and is preferably hinged or pivoted at d to the lever and is connected with the nailcarrier by a ball or equivalent joint 01 The nail-carrier D is arranged to slide in ways 61 from a position to receive nails from the naildistributer d or other nail-delivering mechanism or by hand to a position to deliver nails to the holes of the templet O or to the naildriving devices. A stop 01 limits the extent of outward movement of the nail-carrier D and a stop 01 the extent of its movement in the reverse direction. It will thus be seen that the movement of the nail-carrier from one position to another causes the top-liftfeeding slide to be simultaneously moved from one position to another and that this is true whether the movement is imparted to the slides by means of the handle h of the lever h or whether directly to either of the slides H D. In use the movement of the nail-carrier slide backward from the templet to receive nails causes the top-lift -feeding slide to be advanced to the top-lift carrier and feed a top lift to the holding devices of the top-liftspanking plate, or to the top-lift-spanking plate, and its movement in the reverse direction causes the nail-carrier to be moved into operative relation with the nail-driving devices and the tOpJift-feeding slide to be returned to its original position. For convenience I have represented these movements as being within the control of the operator at the front of the machine, so that by one movement or operation of the operator the nailcarrier is moved into and out of position and a top lift fed to the top-lift carrier or spanking-plate. I would not be understood as limiting the invention to the particular form of the connection between the top-lift-feeding slide and nail-carrier, as the devices herein specified represent only one of many ways by which this connection can be obtained. The top-lift-holding devices represented include the holding-arms and a yielding back gage,

and the top-lift-feeding plate is given, when this form of holder is used, sufficient movement to bring the back edge of the top lift into contact with the rear gage and move it backward sufficiently to permit the breast of any size top lift to be moved within the holding-shoulders of the breast-gages.

It will be understood that with the organization of heeling-machine represented in the drawings the nail-carrier is moved into position before the machine is started, and upon the starting of the machine the last, With the shoe thereon, is moved forcibly against the heel and templet and the nail is driven, and that then the last,with the heeled shoe, drops for an instant and the top-lift-carrier plate is fed into position beneath the templet, bringing the top lift over the heel, and that then the last and heeled shoe are moved upward to spank on the top lift and then immediately dropped again, and the top-lift carrier is returned to its original position and the machine comes to rest. The pressure-cam e upon the shaft 6 makes one revolution; but it is shaped to give during this revolution, by means of the projections 7c and depressions 70 70 two movements to the last-first, the upward movement to compress the heel-blank and hold the same during the driving of the nails; second, the dropping movement; third, the upward movement to spank on the top lift, and, fourth, the dropping movement. The operator, preparatory to starting the machine, moves the nail-carrier back to receive or obtain a load of nails and by this movement also forces a top lift into the top-lift holder of the top-lift spanker and carrier. The jack B comprises a base I), which is horizontally adjustable in ways in the table or bed a, preferably by means of an adjustingserew b, held by the latch-holder 19 secured to the frame of the machine, and the nut 5 fastened to the base b of the jack. has at its rear end a hole 12 of a size to receive the section 19 0f the jack-spindle. From this hole extends a narrow recess b through Which extends a block W, fastened to the sec tion 19 of the spindle by means of a tongue extending into a hole therein and movable vertically with said spindle? This block 5 holds the arms carrying the shoe centering and holding devices or guides M M. (See Fig. 8.) The base of the jack 1) also has at its front end lugs 6 to which is pivoted or hinged the jack-post b the jack-post having the ear b which extends between the lugs and through which and the lugs a stud or shaft 1) extends. The jack-post has the hole (9 for the reception of the upper section 6 of the jack-spindle. This upper section of the spindle has at its upper end a pin b, which enters a hole in the last (1 the last resting upon the collar or shoulder 12 I prefer that the pin-hole b" in the last be sufficiently wide to permit lateral movement of the last in relation to it, and when this construction is employed I prefer to secure the last to the pin in a manner to permit such .sidewise movement of the last thereon by means of a pin or screw b, extending in through a hole Z9 in the side of the last to the spindle-pin Z). The hole I) in the jack-post is in line with the hole 17 of the base of the jack, and the upper section b of the jackspindle bears or rests upon the lower section b of the jack-spindle, and this lower section in turn rests upon the adjusting-nut 6 of the pressure-head 6 The shoe holders and guides M M each comprises a block on, having the curved inner edge m shaped to conform to the curve of the heel end of the last along its back corner and side. This curved face of each block is lined with a thick lining m of rubber or other suitable material. Each of the blocks on is horizontally adj ust- This base able upon its respective holding-arm, each of said arms m at having its upper end m extendinghorizontally and lengthwise the last and having in its upper surface a groove or way m to receive the ton guem upon the under surface of the block m. (See Figs. 2 and 3.) There is also formed in each section m of the arm a long slot through which extends the clamping and adjusting screw m, which screws into a screw-hole in the block am. By loosening the screw the block is adjustable horizontally lengthwise the last upon the arm m and by tightening it the block is fastened to the arm in any desired position. By making the holders curved, as described, so as to not only bear against the sides of the last, but also against the rear corners, they serve as they are closed to press the shoe forward, as well as laterally,upon the last, and therefore act not only to clamp the shoe upon the last,but also as a back-stop to'prevent its being moved backward from the last.

The arms m m are each pivoted at m to the block 19 and they are connected with each other by means of a right and left threaded screw m, which is carried by a standard at of the block b in a manner to prevent it from being moved endwise. This is represented as attained by making the standard forked, providing the enlarged holes therein through which the screw m passes, and mounting upon the screw in the fork a collar m. The arms at m are connected with the screw by means of swivel-nuts m m respectively, (see Fig. 3,) each of the nuts having a short spindle which extends through a hole in its respective holding-arm and has a threaded end to receive a nut. The screw is turned by the handle m", and this handle is represented as connected with the screw by means ofa disk m, fastened to the screw, having in its periphery holes m in one of which the threaded inner end of the handle m screws, the handle being removable from one to the other for the purpose of adjusting the operative position of the arms m m The above description shows that the shoe centering and holding devices are carried by the base of the jack and are horizontally adjustable'with it and are vertically movable with the section Z2 of the jack-spindle and have an opening and 010s ing movementin relation to each other, and the last is movable upon the arc of a circle from between the said shoe-holders outward. By providing the last with this movement it is held, when inclined, in a convenient position for receiving the shoe and also for removing it, being then entirely removed from the shoe holding and centering devices. It

is easily moved from said inclined position into a vertical position between the shoeholders, and as the inclination of the jackspindle from a perpendicular position is variable one way or the other, as desired, it provides a means whereby the level of the last, and therefore of the shoe lengthwise of the last, may be easily varied. The adjustment of the jack-post b and therefore of the jack-spindle 11 is obtained by means of the adjusting-screw n, which passes through a threaded hole 01 in a lug upon the side of the jack-post and bears upon the upper surface of the base I). The end of this adjusting-screw, in other words, furnishes the backstop'for the jack-post when in a vertical or very nearly vertical position.

It is desirable to latch or look thejack-post and its spindle in its two positions-namely, its inclined and vertical onesand this is represented as obtained by means of a flat spring 0, secured to the base I) (see Fig. 2) and having its outer end 0' shaped, substantially as represented in'said figure, to have the rounded or curved surface 0 The jackpost stud or shaft e is keyed or otherwise secured to the jack-post, so that it turns with it, and it extends beyond one side lug of the base and has a pin 0 extending downward which bears upon the upper surface of the spring 0, (see Fig. 2,) and when the jack post and spindle are in a vertical position one section of the spring bears against the end of the pin and serves to hold the jack post locked in such position. When the jack-post is inclined, the shaft or stud b is turned, turning the pin 0 so that it passes over the curved section 0 of the spring upon the other side thereof, and the spring then acts to hold it latched or locked in its inclined position. To move the jack-post spindle and last from one position to the other, I have attached to the stud or shaft Z9 a lever P. The operator by moving this lever downward moves the jack-post and last from a vertical to an inclined position. By moving it upward he moves them from an inclined to a vertical position. A stop 19 upon the jack-post and a stop 19 on the base-lug (see Fig. 2) limit the extent of the outward movement of the jackpost, &c.

To lift the jack spindle, last, and shoeguides independently of the pressure-head for the purpose of centering the heel to the shoe or for any other reason, there is pivoted to the base 5 at r the handle B. This pivot is usually near the end of the stud or shaft b. The inner end 1" of the lever or handle is bent to extend below the block b of the jack, (see Figs. 1 and 2,) and upon the downward movement of the outer end of the handle both sections of the jack-spindle, the last,

and the shoe-holders are moved upward. To

draw the last and spindles downward and maintain them in contact with the pressurehead, so that they shall follow the movements of the pressure-head, I use a spring S, fastened at its upper end to the block b and at its lower end tothe housing of the pressurehead. In use, the last being in its receding position, the operator places the shoe thereon and moves the last from its inclined to its vertical position between the shoe-holders. The shoe-holders by the movement of the handle m" are then closed upon the counter of the boot or shoe upon the last and serve to center the'shoe thereon and to hold it so curely thereto. For certain kinds of work the construction which permits a horizontal movement of the last upon the jack-spindle is desirable, as this enables the shoe-holders to move the shoe and last to an accurate center covered by the outer surfaces of the shoe and not by the inner su'rfaces'of the last, the outer surfaces of the shoe being better sur: faces to center by than the last, because of the variations'in the thickness of the counter of the shoeat its sides. It frequently happens in coarse Work that the counter upon one side is considerably thicker than the counter upon the other. The heel is then placed upon the'insole, or, if a heel-holder be employed, in the heel-holder. The operator having moved the nail-carrier and fed the top lift into the top-lift carrier starts the machine and the'heel is attached and top lift applied, asabove stated. When the machine comes to rest, the shoe-holders are opened and the last removed from between them to its inclined position and the nailed shoe removed. I prefer to use in connection with the lever 77. a spring 25 to act against the same and hold it, with the nail-carrier, in registering position with the templet.

When the heel-holder is employed, I prefer to use a breast-gage V, attached to the side of the top-lift-spanker plate, to extend beneath the templet 0 (see Fig. 11) and longitudinally adjustable upon the plate and a back-gage 1), having a yielding movement in the carriage '0, which is adapted to be ad'- justed crosswise the machine upon the arm 12 of the top-lift lever g by means of a nut and an adjusting-screw v The back gage is provided with a yielding movement in its holding-block by means of the spring 0 Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States- 1.
